FAQ
It depends on how it works.
Using the official LoRaWAN firmware, without sensor as an example and accounting for battery self-discharge:
- Transmit once per hour with a 5-second transmission duration per time, excluding retransmissions caused by poor signal: the device can run for approximately 20 to 30 days.
- If data is sent every 15 seconds under ideal conditions, the device can complete roughly 6,000 transmissions
Almost all LoRa based communications, including Paxcounter, Disaster Radio, Meshtatic, LoRaWAN, LoRa P2P, etc
Considering the overall structure and volume, the Capsule Sensor V3 adopts a built-in antenna, and the communication distance measured in open areas is 2.5Km
Through the Wireless Boot system, you can program it directly through an IDE such as Arduino, or upgrade it using OTA on web pages
Capsule Sensor V3 is compatible with almost all LoRaWAN gateways on the market. You can also choose a Heltec LoRaWAN gateway.
